Oral acetazolamide for worsening heart failure

Chronic Heart Failure

Treatments studied

Part of Heart & circulation clinical trials.

This trial tests whether taking acetazolamide by mouth can help prevent or improve worsening (decompensation) of heart failure after you needed IV water pills (diuretics). It’s mainly for adults with a recent heart-failure flare and specific heart/lab signs, while carefully excluding certain low blood pressure, kidney issues, and electrolyte or acid–base problems.
